Question

In a common-base amplifier, the phase difference between the input signal voltage and the output voltage is

• A. $\frac{\mathrm{\pi }}{2}$
• B. $\frac{\mathrm{\pi }}{4}$
• C. Zero
• D. $\mathrm{\pi }$

Answer 1

The correct option is C

Zero

The explanation for the Correct answer:

Option (C) zero

1. The Common Base Amplifier is a type of bipolar junction transistor configuration where the base terminal of the transistor is a common terminal to both the input and output signals, therefore it is known as a common base.
2. In a common-base amplifier, the phase difference between the input signal voltage and the output voltage is zero.

Hence correct option (C) is correct.
